Abstract: A method is provided for interfacing a plurality of processing components with a shared resource component. A token signal path is provided to allow propagation of a token through the processing components, wherein possession of the token by a given processing component enables the latter to conduct a transaction with the shared resource component. Token processing logic is also provided for propagating the token from one processing component to another along the token signal path, the propagating being done at a propagation rate that is related to a transaction rate associated with the shared resource component. A circuit comprising a plurality of processing components and a shared resource component is provided wherein the plurality processing components and the shared resource components are interfaced with one another using the method proposed.

Abstract: A method is provided for interfacing a plurality of processing components with a shared resource component. A token signal path is provided to allow propagation of a token through the processing components, wherein possession of the token by a given processing component enables the latter to conduct a transaction with the shared resource component. Token processing logic is also provided for propagating the token from one processing component to another along the token signal path, the propagating being done at a propagation rate that is related to a transaction rate associated with the shared resource component. The token processing logic also generates a trigger signal at least in part based on the token and propagates to trigger signal to the shared resource component to convey initiation of a transaction with the shared resource component.

Abstract: A method is provided for propagating clock signals in a circuit segment having a first clocked device, a second clocked device and a data path between the first clocked device and the second clocked device. The data path propagates data released by the first clocked device to the second clocked device and is associated with a data propagation delay. The method comprises providing a clock propagation path for propagating clock signals to the first clocked device and the second clocked device, wherein the clock signal propagated to the second clocked device is delayed from the clock signal propagated to the first clocked device by a clock delay interval, the clock delay interval being related to the data propagation delay of the data path. A circuit segment making use of the above method is also provided.

Abstract: A method and apparatus for reducing echo in a communication system are provided. A first signal including a voice component associated to a speaker is received. The first signal is processed to derive a harmonic feature of the voice component. A second signal including an echo component correlated to the first signal is also received. The second signal is processed at least in part on the basis of the harmonic feature of the voice component to remove at least in part the echo component such as to derive an echo reduced signal. The echo reduced signal is then released. In specific implementations, the harmonic feature of the voice component is an estimate of the pitch associated to the voice component.

Abstract: A spacer (36) made to be installed between two permanently connected discs (31 and 32), without a bolted flange, and comprising axial thrust (43, 47) as well as outer radial thrust (45, 48) alignment surfaces (41). It comprises moreover an outer cover (37) to provide sealing and a cooling passageway, and stiffening tongues (38) which accommodate thrust loads.
